Howdy,
I bought a Stoeger 12-ga Coach gun about twelve years ago and used it once or twice a month for cowboy action. I bought it used from a guy who had used it for three years. I sold it to a guy who is using it on a regular basis. The run like Timex watches.
There are three things that I've had trouble with. I'll agree with Graybeard that the stock makes it feel more like a piece of lumber than a shotgun, but what do you want for $349 at Dick's? The early ones had some sort of stained Brazilian hardwood, but the new ones have walnut stocks.
Second is thye child-proof action-lever spring. I have removed and trimmed about four of them so far. I bought a 20-ga Lady's Uplander for my daughter to use when she was eleven. She couldn't get it open. I could, but my thumb turned red and retained the checkering impressions all day. I recently bought a like new 26" 12-ga Uplander w/ tubes and it seems that they have changed spring suppliers. The gun is much easier to open and I haven't had to pull the stock off.
Last is the way the firing-pin bushings will loosen and begin unscrewing from the breechfaces. This can be fixed with a little Loctite.
Stoeger Uplanders are simple, reliable, and strong shotguns that will do a good job for you, but won't win any beauty contests. I bought my last one just so I'd have something with 3" chambers that I won't worry about in a rainy duck-blind. The choke-tube threads are Mossberg, so replacements are inexpensive. I would go with the double-trigger version so you can pick your barrel.
Good luck,
Bitterroot
